With my latest texture for V4.1 I used the blender Node, and a pubic hair mask, in Poser 6 as an option to add or remove pubic hair, as well as change color. With the texture I am working on now I am using the blender node for both the eyebrows and Pubic hair. Unfortunately if you use DAZ studio, I don't think there is an equivalent to the blender node ;-(  

I personally like having both options in a texture package. One option for painted on hair, brows and pubes, and an option to use transmaps/mask.
